2014 INFINITI QX80 power

towing. For example, towing a heavy trailer
in high outside temperatures on graded
roads can affect engine performance and
cause overheating. The transmission high
fluid temperature and engine protection
mode, which helps reduce the chance of
transmission and engine damage, could
activate and automatically decrease engine
power. Vehicle speed may decrease under
high load. Plan your trip carefully to
account for trailer and vehicle load, weath-
er and road conditions.
WARNING
Overheating can result in reduced engine
power and vehicle speed. The reduced speed
may be lower than other traffic, which could
increase the chance of a collision. Be
especially careful when driving. If the
vehicle cannot maintain a safe driving
speed, pull to the side of the road in a safe
area. Allow the engine to cool and return to
normal operation. See“If your vehicle over-
heats” in the“6. In case of emergency”
section of this manual.
CAUTION
Vehicle damage resulting from improper
towing procedures is not covered by INFINITI
warranties.

Tongue load
When using a weight carrying or a weight
distributing hitch, keep the tongue load
between 10 to 15% of the total trailer load
or use the trailer tongue load specified by
the trailer manufacturer. The tongue load
must be within the maximum tongue load
limits shown in the following “Towing
Load/Specification” chart. If the tongue
load becomes excessive, rearrange cargo
to allow for proper tongue load.
Technical and consumer information9-19

10,000 lb (4,545 kg). A weight distributing
hitch should be used to tow trailers that
weigh over 5,000 lb (2,267 kg).
Your vehicle may be equipped with Class IV
trailer hitch equipment that has a 10,000
lb (4,545 kg) maximum weight rating, but
your vehicle is only capable of towing the
maximum trailer weights shown in the
“Towing Load/Specification”chart earlier
in this section.
CAUTION
. Do not use axle-mounted hitches.
. Do not modify the vehicle exhaust
system, brake system, etc.
. Do not attach any additional hitches to
your vehicle because a hitch is already
mounted to your vehicle frame.
Tire pressures
.When towing a trailer, inflate the
vehicle tires to the recommended
cold tire pressure indicated on the
Tire and Loading Information la-
bel.
.Trailer tire condition, size, loadrating and proper inflation pres-
sure should be in accordance with
the trailer and tire manufacturers’
specifications.
Safety chains
Always use a suitable chain between your
vehicle and the trailer. The safety chains
should be crossed and should be attached
to the hitch, not to the vehicle bumper or
axle. Be sure to leave enough slack in the
chains to permit turning corners.
STI0745
Trailer lights
Your vehicle is equipped with a towing
package, which also includes the 7-pin
trailer harness connector located under the
trailer hitch cover on the rear bumper.
CAUTION
. When splicing into the vehicle electrical
system, a commercially available power-
type module/converter must be used to
provide power for all trailer lighting. This
unit uses the vehicle battery as a direct
power source for all trailer lights while
Technical and consumer information9-25

9-26Technical and consumer information
using the vehicle tail light, stoplight and
turn signal circuits as a signal source.
The module/converter must draw no
more than 15 milliamps from the stop
and tail lamp circuits. Using a module/
converter that exceeds these power
requirements may damage the vehicle’s
electrical system. See a reputable trailer
retailer to obtain the proper equipment
and to have it installed.
. Do not connect electrical devices that
draw more than 40 amps to the vehicle.
The fusible link may melt.
Trailer lights should comply with federal
and/or local regulations. For assistance in
hooking up trailer lights, contact an
INFINITI retailer or reputable trailer retailer.
Trailer brakes
When towing a trailer load of 3,500 lbs.
(1,587 kg) or more, trailers with a brake
system MUST be used. However, most
states require a separate braking system
on trailers with a loaded weight above a
specific amount. Make sure the trailer
meets the local regulations and the regula-
tions where you plan to tow.
Several types of braking systems are available.
Surge Brakes -
The surge brake actuator is
mounted on the trailer tongue with a
hydraulic line running to each trailer
wheel. Surge brakes are activated by the
trailer pushing against the hitch ball when
the tow vehicle is braking. Hydraulic surge
brakes are common on rental trailers and
some boat trailers. In this type of system,
there is no hydraulic or electric connection
for brake operation between the tow
vehicle and the trailer.
Electric Trailer Brakes - Electric braking
systems are activated by an electronic
signal sent from a trailer brake controller
(special brake sensing module).
Have a professional supplier of towing
equipment make sure the trailer brakes are
properly installed and demonstrate proper
brake function testing.
WARNING
Never connect a trailer brake system directly
to the vehicle brake system.
Pre-towing tips
. Be certain your vehicle maintains a level
position when a loaded or unloaded
trailer is hitched. Do not drive the
vehicle if it has an abnormal nose-up
or nose-down condition; check for
improper tongue load, overload, worn
suspension or other possible causes of
either condition.
. Always secure items in the trailer to
prevent load shift while driving.
. Keep the cargo load as low as possible
in the trailer to keep the trailer center of
gravity low.
. Load the trailer so approximately 60%
of the trailer load is in the front half and
40% is in the back half. Also make sure
the load is balanced side to side.
. Check your hitch, trailer tire pressure,
vehicle tire pressure, trailer light opera-
tion, and trailer wheel lug nuts every
time you attach a trailer to the vehicle.
. Be certain your rearview mirrors con-
form to all federal, state or local
regulations. If not, install any mirrors
required for towing before driving the
vehicle.
. Determine the overall height of the
vehicle and trailer so the required

tail pipe or rear bumper.
. Make sure you disconnect the trailer
lights before backing the trailer into the
water or the trailer lights may burn out.
When towing a trailer, the transmission
fluid should be changed more frequently.
For additional information, see the INFINITI
Service and Maintenance Guide.
TOW mode
Using TOW mode is recommended when
pulling a heavy trailer or hauling a heavy
load. Push the TOW MODE switch to
activate tow mode. The TOW MODE indi-
cator light in the meter illuminates when
TOW mode is selected. Push the TOW
MODE switch again to turn TOW mode off.
TOW mode is automatically cancelled when
the ignition switch is placed in the OFF
position.
TOW mode includes the following features:
. Grade logic —Adjusts transmission
shifts when pulling a trailer or hauling
a load up a grade.
. Downhill Speed Control (DSC) —auto-
matically downshifts when driving
down a grade with a trailer or heavy
load to help control vehicle speed. Driving the vehicle in the TOW mode with
no trailer/load or light trailer/light load will
not cause any damage. However, fuel
economy may be reduced and the trans-
mission/engine driving characteristics may
feel unusual.
When towing a trailer, the transmission
fluid should be changed more frequently.
For additional information, see the INFINITI
Service and Maintenance Guide.FLAT TOWING
Towing your vehicle with all four wheels on
the ground is sometimes called flat towing.
This method is sometimes used when
towing a vehicle behind a recreational
vehicle, such as a motor home.
CAUTION
.
Failure to follow these guidelines can
result in severe transmission damage.
. Whenever flat towing your vehicle, al-
ways tow forward, never backward.
. DO NOT tow any automatic transmission
vehicle with all four wheels on the
ground (flat towing). Doing so WILL
DAMAGE internal transmission parts due to lack of transmission lubrication.
. DO NOT tow an Four-Wheel Drive (4WD)
vehicle with any of the wheels on the
ground. Doing so may cause serious and
expensive damage to the powertrain.
. For emergency towing procedures refer
to“Towing recommended by INFINITI” in
the “6. In case of emergency” section of
this manual.
Automatic Transmission
Four-Wheel Drive (4WD) models:
Do not tow a 4WD vehicle with any of the
wheels on the ground.
Two-Wheel Drive (2WD) models:
To tow a vehicle equipped with an auto-
matic transmission, an appropriate vehicle
dolly MUST be placed under the towed
vehicle’s drive wheels. Alwaysfollow the
dolly manufacturer’ s recommendations
when using their product.

361-4792.WARNING
A vehicle equipped with Four-Wheel Drive
(4WD) should never be tested using a two
wheel dynamometer (such as the dynam-
ometers used by some states for emissions
testing), or similar equipment. Make sure
you inform test facility personnel that your
vehicle is equipped with 4WD before it is
placed on a dynamometer. Using the wrong
test equipment may result in transmission
damage or unexpected vehicle movement
which could result in serious vehicle da-
mage or personal injury.
Due to legal requirements in some states
and Canadian Provinces, your vehicle may
be required to be in what is called the
“ready condition”
for an Inspection/Main-
tenance (I/M) test of the emission control
system.
The vehicle is set to the “ready condition”
when it is driven through certain driving
patterns. Usually, the “ready condition”
can be obtained by ordinary usage of the
vehicle.
If a powertrain system component is
repaired or the battery is disconnected,
